tableDigital
The ocean acidification diel suite is an autonomous instrument package that measures diel variability in coral reef seawater carbonate chemistry. Diel suite surveys are conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) within coral reef ecosystems across the Pacific Islands Region as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The data provided in this record are from diel suites deployed across the Hawaiian Archipelago since 2016 during ESD-led NCRMP missions. Specifically, at select sites at Kure Atoll and Lisianski Island between September 14th - 26th, 2016 as well as Lanai and the Main Hawaiian Islands between July 10th - July 30th, 2019.
Diel suites were deployed on the reef for at least 24 hours to measure in-situ salinity, temperature, pressure, pH, and current direction and magnitude. Seawater samples were also collected for laboratory analyses of dissolved inorganic carbon (DIC) and total alkalinity (TA). Components of the carbonate system--including pH, pCO2 (partial pressure of carbon dioxide), and aragonite saturation state--are calculated from DIC, TA, temperature, salinity and pressure. Each diel suite consisted of: 1 SBE-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, and up to 9 Programmable Underwater Collectors (PUCs), each of which collected 1 water sample at 4-hour intervals; however, only data from the CTD and water samples were recovered from the diel surveys at Kure and Lisianski in 2016. Starting 2018, 1 SBE-43 oxygen sensor was tethered to the CTD sensor for diel surveys. Stand-alone dissolved oxygen (DO) and photosynthetically active radiation (PAR) loggers were included with the diel suite deployments starting HARAMP 2019. Instruments deployed, samples collected, and sample intervals are recorded in the summary file enclosed with the data package, and exceptions to the standard diel suite are also noted.
Manual seawater sampling and other National Coral Reef Monitoring Program (NCRMP) field monitoring efforts are limited to daylight hour operations. As a result, these data sets do not capture full 24-hour variability in coral reef physical and chemical environments. The ocean acidification diel suite was developed to increase the temporal resolution and coverage of oceanographic and carbonate chemistry measurements and contextualize daytime sampling within the full diel cycle.

The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis.
NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the Coral Reef Conservation Program (CRCP) and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML), NOAA Coral Reef Watch, and many other partners. The Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading in-situ climate monitoring in the U.S. Pacific Islands Region.
The climate component of NCRMP in the Pacific provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. Each year, ESD scientists work closely with CRCP and partners during Reef Assessment and Monitoring Program (RAMP) missions to collect data using moored oceanographic and ecological instruments stationed at fixed sites in the Pacific Ocean, and water samples collected by divers. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region’s resources and how they are changing over time.

Representativeness
Seawater carbonate chemistry at the benthos is dynamic and driven by physical and biological processes occurring at time scales of minutes to days. The measurements and analyses from this instrument suite is representative of the water column chemistry at the time of measurement, but this highly variable environment allows for a fairly wide distribution of measured values.
Accuracy
Water samples: accuracy of seawater carbonate chemistry laboratory analysis is explained in detail in Dickson et al (2007), SOP #2: Determination of total dissolved inorganic carbon in sea water, and SOP #3b: Determination of total alkalinity in sea water using an open-cell titration.
Satlantic SeaFET Ocean pH sensor: measurement range: 6.5-9.0 pH; salinity range: 2-40 psu; accuracy: +/- 0.05 pH; precision: better than 0.001 pH; resolution: 0.0001 pH; stability: 0.005 pH/mo
SBE-19plus CTD sensor:
Conductivity - measurement range: 0-9 S/m; accuracy: +/- 0.0005 S/m; stability: 0.0003 S/m per month; resolution: 0.00005 S/m;
Temperature - measurement range: -5-35 deg C; accuracy: +/-0.005 deg C; stability: 0.0002 deg C per month; resolution: 0.0001 deg C;
Pressure - measurement range: 0-600 m; accuracy: +/- 0.1%; stability: +/- 0.1%; resolution: 0.002%
Nortek Acoustic Doppler Current Profiler 1MHz: Profiling range: 12-25 m; accuracy: +/- 1%
SBE-43 oxygen sensor: Measurement range: 120% surface saturation; accuracy: +/- 2% of saturation; stability: 0.5% per 1000 hours
RBRsolo³ DO logger: Range: 0 to 600%, Accuracy: ±2% O2 saturation, Resolution: 1% of saturation, Response time: ~10s, (T90%)
RBRsolo³ PAR logger: Depth rating: 350/560m, Sampling capacity: ~13M readings, Sampling rate: 1s to 24h and 2Hz
Analytical Accuracy
For some deployments, paired water samples are collected simultaneously at the benthos and 1.5 meters above the seafloor.
Completeness Measure
The entire suite of instrumentation is deployed during diel surveys; however, various issues can occur with any one or several of the instruments during the deployment thereby limiting the data recovered.
While PUCs are programmed to collect water on this regular sampling schedule, issues with the pumps can occasionally result in missing samples for some of the time steps.
Refer to the 'meta' file enclosed with the data package for details. In 2016, only CTD and water quality data were recovered from the diel surveys at Kure and Lisianski.
Field Precision
Redundant data are collected to ensure accuracy of the methods/instrumentation. For some deployments, paired water samples are collected simultaneously at the benthos and 1.5 meters above the seafloor.
Completeness Report
All analyzed samples and measured values are included. NULL values in the data, where they exist, indicate that the observation/analysis was not conducted for the sample record where it appears.
Conceptual Consistency
The data are very consistent, sample collection and processing protocols detailed in Dickson et al (2007) are adhered to rigorously, both in the field (SOP #1) and in the laboratory (SOP #2 and #3b).
The Ocean Acidification Diurnal Suite is a collection of instruments deployed by SCUBA divers onto the seafloor that makes autonomous measurements and collects seawater samples. For a typical 24 hour sampling, the diurnal suite consists of: 1 Sea Bird Electronics (SBE)-19plus CTD sensor, 1 Nortek Acoustic Doppler Current Profiler (ADCP), 1 Satlantic SeaFET Ocean pH sensor, and 7 Programmable Underwater Collectors (PUC), where each PUC collects 1 discrete water sample at a 4-hour interval from 12:00 on day 1 to 12:00 on day 2. Starting 2018 an oxygen sensor was co-located with the CTD sensor, and beginning in 2019 a stand-alone PAR sensor as well as oxygen sensor were added to the deployment. All instruments are weighted or zip-tied to rubble on the seafloor, or both, to secure the position of the instrumentation for the duration of the deployment.
Instruments 3-7 were not in the diel suite package for the 2016 deployment.
Water samples collected with Programmable Underwater Collectors (PUC)
Developed by Dr. Chris Langdon's laboratory at the University of Miami, PUCs are computerized timers attached to a low-power peristaltic pump. An array of PUCs collects water samples at 4-hour intervals over the course of at least 24-hours, usually starting at 12:00 pm local time on day 1 and ending at 12:00 pm on day 2. While PUCs are programmed to collect water on this regular sampling schedule, issues with the pumps can occasionally result in missing samples for some of the time steps. For some deployments, paired water samples were collected simultaneously at the benthos and 1.5 meters above the seafloor.
Samples are collected underwater in tedlar bags pre-poisoned with mercuric chloride and transferred to glass bottles within a few hours of recovery. Water samples are analyzed for DIC using a coulometer (SOP #2) and for TA using a titrator (SPO #3b) by the NOAA Pacific Marine Environmental Laboratory. On occasion, poor pump performance results in half-filled sample bags. These samples are only analyzed for TA due to insufficient sample volume for DIC analysis. Full carbon system chemistry values (including pH, pCO2, and aragonite saturation state) are derived from DIC/TA and salinity/temperature/pressure data from a co-deployed CTD using the R package seacarb.

Conductivity-Temperature-Depth (CTD) sensor
CTD data are collected by a Sea Bird Electronics 19plus v2 SeaCAT every 2 minutes. Data are uploaded as HEX files, converted to CNV using SBE Data Processing Software, and converted to CSV using the 'oce' package in R. Depth in CTD csv file is that logged by the CTD itself (the depth in other csv files is that of the deployed depth as read by dive computer)

hannah.barkley@noaa.gov
processor
Acoustic Doppler Current Profiler (ADCP) sensor
The diel suite includes either a 1.0 MHz or a 2.0 MHz side-looking ADCP (1.0 MHz ranges 20-m depth, while the 2.0 MHz ranges 10-m). ADCP measurements are collected at 2 minute intervals and binned by height above the sensor. Each height bin is represented in the data set as the upper limit of the bin height above the sensor on the seafloor (e.g., a 1.4 m bin represents current data collected between 0.4 m and 1.4 m above the ADCP). ADCP data include a blanking region, or a small distance in front of the transducer in which measurements cannot be made, of 0.2-0.4 m. Current data are grouped into 1-m height bins.
Raw data downloaded from the ADCP are processed in R using the oce package. XYZ coordinate data are converted to ENU (east-north-up) coordinate system. Current speed is calculated as the square root of the sum of the squared u and v velocities and direction as the arctan(v/u). Data are trimmed to a maximum height bin for each time step using pressure data to remove above-water signal. As a result, NULL values may exist for larger height bins above the surface of the water due to waves and tides.

SeaFET pH sensor
The SeaFET pH measures in-situ pH using a solid state ISFET sensor with an AgCl external reference electrode. The electrode is conditioned in running seawater up to a week prior to deployment and stored in artificial seawater between deployments. pH data are collected in bursts of 30 measurements every 5 minutes. The SeaFET is co-deployed with a CTD, and temperature and salinity values from the CTD time series are used to correct the raw pH time series. The SeaFET derives pH from both internal and external potentiometric cells, but only external pH is reported. SeaFET pH values are compared to pH values calculated from discrete TA and DIC samples collected at the same time and location.

SBE 19plus V2
conductivity, temperature, depth
The SBE 19plus V2 (Version 2) SEACAT Profiler measures conductivity, temperature, and pressure (depth) and provides high accuracy and resolution, reliability, and ease-of-use for a wide range of research, monitoring, and engineering applications. The pump-controlled, TC-ducted flow configuration minimizes salinity spiking caused by ship heave and allows for slow descent rates without slowing sensor responses, improving dynamic accuracy and resolving small scale structure in the water column.
Programmable Underwater Collector (PUC)
Water Sampler
Programmable Underwater Collectors (PUC) are computerized timers attached to a low-power peristaltic pump to collect water samples at episodic intervals (i.e., every 4 hrs over a 24-hr period). Designed and Developed by Dr. Chris Langdon’s laboratory at the University of Miami, Rosenstiel School of Marine and Atmospheric Science.
SeaFET v2
Ocean pH Sensor
SeaFET v2 Ocean pH Sensor measures in-situ pH using a solid state ISFET sensor with an AgCl external reference electrode.
Aquadopp Profiler
acoustic doppler current profiler (ADCP)
Current profiler: Nortek Aquadopp Profiler 1 MHz or 2 MHz. Small and compact, with up to 25 m or 40 m current profiling range, respectively.
SBE 43 DO Sensor
Dissolved Oxygen Sensor
The SBE 43 is an individually calibrated, high-accuracy oxygen sensor to assist in critical hypoxia and ocean stoichiometric oxygen chemistry research on a variety of profiling and moored platforms. The SBE 43 is designed for use in a CTD’s pumped flow path, providing optimal correlation with CTD measurements. Elapsed time between the CTD and associated oxygen measurement is easily quantified, and corrected for, in post-processing. The black plenum and plumbing’s black tubing blocks light, reducing in-situ algal growth. Plumbing isolates the SBE 43 from continuous exposure to the external environment, allowing trapped water to go anoxic and minimizing electrolyte consumption between samples for moored deployments.
RBRsolo³ DO logger
Dissolved Oxygen Sensor
RBRsolo³ DO dissolved oxygen recorder (OxyGuard® Ocean DO) is a compact, lightweight single channel logger for depths up to 1700m, standard sampling from 1s to 24 h and 2Hz,
RBRsolo³ PAR
PAR sensor
RBRsolo³ PAR recorder is a compact and lightweight single channel recorder for depths up to 350 or 560m with sampling capacity of ~13M readings and sampling rate of 2, 4, 8, 16, or 32 Hz. A photosynthetically active radiation (PAR) sensor measures the spectral range of light available for photosynthesis.
Diel Suite
The Ocean Acidification Diel Suite is not a physical platform (boat, buoy, etc.), but rather a collection of instruments deployed together on the seafloor that makes autonomous measurements and collects seawater samples, which allows for the quantification of 24-hr variability in seawater carbonate chemistry present at the reef.
